This system automatically and effectively controls each unit to provide individual rooms of different sizes with a comfortable working orliving environment.5-3 Year round cooling and/or heatingVRVII & VRV-WII• Designed to provide simultaneous year round cooling and/or heating, VRVII heat reovery systems are modular in concept and are therefore, idealfor use in rooms or zones that generate varying thermal loads according to building orientation or local cold or hot spots.VRVII & VRV-WII• It is possible for the same meeting room to give rise to differing thermal loads depending on the time of day, number of occupants present, locationand usage pattern of lighting and electronic office equipment.VRVII & VRV-WII• Until the advent of the VRV, a complex 4-pipe fan coil was needed to meet this requirement. The VRV however, is easier to design and install an inits heat recovery format, can conserve energy in two or more rooms at the same time.VRV-WII• The colder it is outside, the warmer it needs to be indoors, which means that the capacity of the air-cooled outdoor unit drops. Water-cooled airconditioners are not subject to this problem. The boiler ensures that sufficient enough additional heat is always available indoors.Room layout changeIndoor unitadditionOfficeReception roomStock roomOfficeMeeting roomMeeting roomMeeting roomMeeting room
